pneumoconiosis

Zhang Haichao was twenty-eight when he got pneumoconiosis. He was fit and well before he started working at an abrasive-materials factory in Xinmi, not far from Zhengzhou, the capital of Henan, where he comes from. On the job, he inhaled a huge amount of dust every day. In the second half of 2007, he began to cough and felt short of breath.
